2 Claims.

The invention relates to registering devices and more particularly to devices for registering telephone calls. It has for one of its objects to provide a device on which a permanent record may be kept of the telephone call made during a given period'. Another object is to construct the device as af coin depository so that a coin may be deposited for each call made. Still another object is to' so construct the device that the depositing of the coin will actuate the registering mechanism and at the same time indicate the total sum deposited. A further object is to form the device in a shape suitable for supporting a telephone index, writing pad, or the like. A still further object is to provide a registering device of strong construction, pleasing appearance, simple in its operation, and comparatively inexpensive to manufacture.

These and other objects and advantages will be readily understood from the following description andA from the accompanying drawing of a preferred embodiment in which, however, modifications may be made without departing from the scope of the appended claims.

In the drawing Fig. 1 is a plan view of the preferred embodiment of the registering device,

Fig. 2 a bottom view with the base plate partly broken away,

Fig. 3 a cross-sectional side view taken on line 3-3 in Fig. 1,

Fig. 4 a cross-sectional rear view taken on line 4 4 in Fig. 2,

Fig. 5 a cross-sectional front view taken on line 5-5 in Fig. 2, and

Fig. 6 a fragmental view showing the action of a certain part.

Referring now to all the views, simultaneously, the device consists of a casing 10 secured on a base plate l1. In the embodiment illustrated, the front part of the casing is slightly slanting and on this part is mounted an index 12 in such a manner that the leaves thereof may be consulted without removing it from the base.

Two numeral wheels 13 and 14 are mounted in the top of the casing and near its rear end on studs 15 and 16; they are free to rotate on these studs. Both these wheels are provided with downwardly extending teeth 1'7 and the wheel 13 is also provided with a radial tooth 18 which engages between the teeth of the wheel 14 at each complete revolution. The upper faces of the wheels are imprinted with numerals from 0 to 9 and these numerals are successively shown, through openings 19 and 20 punched in the casing, as the wheels are turned. A coin slot 21 is also punched in the casing. Y y

A lever 22 of triangularl shape is mounted on a stud 23 which is securedv in a partition'24 inserted in the casing. One end of this ylever extends partly under the coin sloty and is bifurcat'ed at its upper face solas to form a groove 25 into which a coin 26 may drop. f The lower end of the lever is provided with a pin 27 which passes through a curved slot 28 in the partition 24 and engagesv in a straight slot -29 which is punched vertically in a plate 30. This plate is slidably mounted on the partition byv means of two studs 31 and 32 .which arer riveted on the plate and engage in slots 33 and34 punched in the partition.

Two bearings 35 and 36 are formed on the sliding plate and in these bearings a rocker arm 37 is mounted. The upper end of this arm is bent sidewardly to form a pawl 38 which engages between the teeth of the numeral Wheel 13. A flat spring 39 has its lower end riveted to the sliding plate While its upper end holds the pawl in contact with the teeth of the numeral wheel. In Fig. 2 the pawl is shown in the position it would occupy immediately after its angular face had passed by the tooth marked A. A tension spring 40 is connected between a spring post 41 formed on the sliding plate and a hook 4l secured on the casing. It tends to hold the sliding plate in the position shown in Fig. 2.

The operation of the device will now be described. When a coin is inserted in the coin slot and pressed down, the lever 22 is actuated and the pin 27, which is secured in the lower end of the lever and engaged in the slot 29 in the sliding plate, causes this plate to slide sidewardly. As the pawl 38 is mounted on the plate, the movement of the plate is imparted to it. As the pawl moves it successively engages with the teeth of the numeral wheel 13 and consequently turns this wheel, one tooth at a time. The numeral wheels each have ten teeth. Each time the wheel 13, which carries numerals representing units, turns one revolution the tooth 18 engages with one of the teeth on the Wheel 14 and turns this onetenth of a revolution. The numerals on this wheel represent tens. Two flat springs 43 and 44 engage in the teeth of the wheels to prevent accidental rotation or over rotation.

Referring now to Fig. 6, it will be noted that as the coin is pressed down in the coin slot a point is reached when the center of the coin is below the line 45 drawn between one end of the coin slot and the outer corner of the lever 26. At this point the coin will be forcibly injected into the coin chamber 46 by the action of the spring 40 which tends to restore all the parts to their inactive positions.

As the parts are restored the paWl is drawn back of the next tooth, ready to turn the Wheel again when another coin is inserted. From this it will be seen that the numerals shown through the openings 19 and 20 indicate the number of coins deposited in the device or, if a coin is inserted each time a telephone call is made, the number of calls made.

While I have described the device as actuated by a coin, it will be understood that it may be altered so that the lever would extend outside the casing and thus be operated directly without the use of a coin. Or a round hole might be substituted for the coin slot so that the end of a pencil, for example, may be inserted to actuate the lever. However, I prefer to employ a coin, and preferably a dime. By using a dime, not only are the number of calls registered but the total amount of money deposited is indicated as well. I accomplish this by imprinting a zero mark on the casing, as shown at 47, and a S mark, as shown at 48. The numerals shown through the openings together with the zero mark now indicate the sum deposited. By imprinting a bracket-shaped frame 49, containing the word Amount and another bracket-shaped frame 50 containing the word Calls, it is readily indicated which number to read.

A handle 52 is attached to the sliding plate 30 and extends into the coin chamber through a slot 53 which is cut in the partition 24. The end of this handle is reached through the door opening 54 through which the coins are also removed. The door has been omitted from the drawing. After the coins are removed from the coin chamber, the numeral wheels are reset by repeatedly moving the handle 52 in the direction indicated by the arrow 55.

While I have described and illustrated a device particularly adapted for registering telephone calls, I do not thereby wish to limit it to such use only but intend to use it for any registering purpose ior which it may be adapted.

Having described my invention, what I claim as new and wish to protect by Letters Patent is:

1. A registering device of the class described comprising a casing, a partition for separating said casing into a front and a rear compartment, a plurality of numeral wheels mounted horizontally in the top of the rear compartment and having their numerals exposed through openings formed in the top of the casing, an opening formed in top of the casing adjacent to the front side of t e said partition, an operating lever pivoted on said partition and having its operating end located under said last-mentioned opening, a slide mounted on the rear side of said partition and connected with and operated by the depression of said operating lever, and a springactuated 'pa-wl mounted on said slide for actuating the numeral Wheels when the operating lever depressed.

2. A registering device of the class described comprising a casing, a partition for separating said casing into a iront and a rear compartment, the front compartment constituting a coin receptacle, a plurality of numeral wheels mounted horizontally in the top of the rear compartment, openi gs formed in the iop of the casing through which the numerals on the numeral wheels are exposed, coin slot formed in the top of the casing adiacent to the front side of the said partition, an operating lever pivoted on said partition and having its operating end located under said coin slot, a slide mounted on the rear side of the partition and connected with and operated by the depression of the operating lever, and a spring-actuated pawl mounted on said slide for actuating the numeral Wheels when the operating lever is depressed by the insertion of a. coin in the coin slot.
